Description

Solid state relays, 1-phase 3RF2 width 22.5 mm, 20 A 48-460 V / 110-230 V AC Ring cable connection SIRIUS 3RF21 solid state relays for switching resistive/inductive loads, e.g. of radiators or valves in a filling plant.
The devices are wear-free and silent and are ideal for noise-sensitive areas (offices, hospitals). They are extremely reliable even at high switching frequencies. The compact design saves space on the cooling surface. The solid-state relays can also be expanded by simply clicking on the standardized 3RF29 function modules for a wide range of applications. The devices are approved worldwide (e.g. IEC and UL/CSA).
The solid-state relays are available as single-phase devices in two widths or as 3-phase devices. They are available for different power ratings and rated operating voltages. Designed for AC or DC operation, they are available with screw, spring-loaded or ring cable lug connection.
In addition to the 3RF29 function modules, control plugs and terminal covers are also available as accessories.
Simple, efficient, always up-to-date - the SIRIUS modular system.
